Beneficiation definition is - the treatment of raw material (such as iron ore) to improve physical or chemical properties especially in preparation for smelting.

Beneficiation is the separation of ore constituents into economically valuable components. For raw gypsum ore, beneficiation consists of separating the ore into its three main constituents: gypsum (calcium sulfate dihydrate), clay (calcium bentonite), and quartz (silicon dioxide).

The clay with its absorbed reagent can then be washed out in the classifier overflow and discarded as waste. Usually 2 to 5 pounds of clay per ton of the concentrate added to the agitator is sufficient to de-reagentize the feldspar. Feldspar Beneficiation Process Feldspar Market Specifications

The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens.

Clay impurities associated with bauxite negatively affect the Bayer process for alumina production. These impurities should be removed as far as possible by a beneficiation technique before the ore is used as feed for the Bayer process. In this current investigation, bauxite washing was conducted in the laboratory. Bauxite washing is a physical process that causes the disintegration and ...

Beneficiation and mineral processing of clay minerals. Clays are categorized into six groups: 1) Kaolin or China clay: white, claylike material composed mainly of kaolinite industrial applications: paper coating and filling, refractories, fiberglass and insulation, rubber, paint, ceramics, and chemicals 2) Ball clay: is a sedimentary clay of fine particle size containing complex ...
